This application claims priority from U.S. Provisional Patent Application serial No. 60/270,042 filed Feb. 20, 2001; the disclosures of which are incorporated herein by reference.
1. Technical Field
The present invention generally relates to hangers and, more particularly, to hangers used to suspend sheet metal ducts from wooden beams or other support members. Specifically, the invention relates to a hanger that may be used in a left hand or right hand configuration and may be used back-to-back.
2. Background Information
Various types of duct hangers are known in the art. Each type of duct hanger presents at least one disadvantage to the person installing and using the duct hanger. Some duct hangers can only be used on the left or right hand side of the duct requiring the user to segregate the hangers. Other hangers include projections that prevent them from hanging side-by-side ducts because the hanger would interfere with the adjacent hanger. Still other duct hangers cannot be installed between existing ducts because of their configuration. The art desires a duct hanger that overcomes these drawbacks and provides a secure mounting arrangement for a duct.
The invention provides a hanger that is used to connect a duct to a support. The hanger includes a main shaft that has a hook disposed at one end of the shaft. The hook is adapted to engage the duct to support the duct. A loop is disposed at the other end of the shaft. The loop is adapted to receive a connector that connects the hanger to the support.
In one embodiment, the hook projects substantially perpendicular from the shaft such that it engages the bottom of the duct. Other embodiments include a pointed hook adapted to puncture the duct.
The invention also provides a hanger having a flat rear surface so that the hangers may be positioned in a back-to-back relationship.
Similar numbers refer to similar elements throughout the specification.
The first embodiment of the duct hanger is indicated generally by the numeral 10 in
Each duct hanger 10 includes a body having a main shaft 20, a hook 22 disposed at one end of shaft 20 and a loop 24 disposed at the other end of shafts 20. Hook 22 is configured to interact with duct 12 to support ducts 12. Loop 24 is configured to interact with a connector 26 that mounts hanger 10 to support 14. Shaft 20 defines at least one opening 28 that allows a connector 30 to connect shaft 20 to duct 12 as depicted in
Loop 24 includes a rolled portion 40 and a tongue portion 42. Tongue portion 42 doubles back on shaft 20 and lies closely adjacent or directly against shaft 20. Rolled portion 40 defines an opening 44 that allows connector 26 to pass through loop 24 to hang duct hanger 10 on support 14. Duct hanger 10 is configured to be used with a typical nail having a broad head that may be readily and easily nailed into support 14. In other embodiments, duct hanger 10 may be supported by screws, pins, pegs, hooks, and the like. When connector 26 is used, the head of nail 26 is larger than openings 44 so that duct hanger 10 cannot fall off of connector 26 after connector 26 is embedded within support 14.
The rear surface of shaft 20 is preferably straight at loop 24 so that pairs of duct brackets 10 may be used back-to-back as shown in FIG. 14. Rolled portion 40 is rolled upwardly away from shaft 20 to permit this configuration.
Duct brackets 10 may be installed by first connecting brackets 10 to support 14 with connectors 26 as depicted in FIG. 3. In the embodiment of the invention depicted in
The second embodiment of the duct hanger of the present invention is indicated generally by the numeral 100 in
In each of the embodiments of the duct hanger described above, the duct hanger may be used on the left or right hand side of duct 12. Duct hangers 10 and 120 may be used with ducts having different heights by altering the location of connector 26 in support 14. Each duct hanger 10, 100, and 120 may be installed in a back-to-back mounting configuration. Each duct hanger does not have to be embedded into support 14. Another advantage is that loop 24 is thin enough and has a profile that allows each duct hanger 10, 100, and 120 to be slid up between adjacent ducts 12 when necessary.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
Moreover, the description and illustration of the invention is an example and the invention is not limited to the exact details shown or described.
